That wasn't the intention, the question is, what did it give you?
Eternia can be completed quite easily in one go.
I don't have the audacity to ask for money for a map for a game that's 17 years old. Although, yes, I have ideas for another map.
And it's not about having to ask. Let's just create a thread to find out if there are people willing to sponsor the creation of a new map (and to what extent).
By the way, the age of the game actually plays a positive role here. Definitely, schoolchildren are unlikely to play Heroes 3 – I think it's mostly adults, who are quite well-off. It's unlikely that most of them will find it difficult to donate 5-10k to the author.
